Just curious as to your DVC point journeys and why you made the journey that you did.
1 - How many points do you have?
We signed contract for 150 but before it closed we bumped it up to 200
2 - Why this number? (how large a family, how many vacations per year,...)
Family of 4 (DD, DW, DD11, DD15) We do a Disney trip of some kind each year. The honest truth is we bought this amount based on our meeting with our DVC sales agent. He asked how we normally vacation and we told him that because of my work, we would stay almost exclusively Sun-Thur (or maybe Fri). We usually go in the spring, so we looked at point demands and he recommended a min of 150. We bumped it to give us more flexibility
3 - How many times have you added on?
Here is where our dilemna is right now. We wanted to add on a couple years ago, when suddenly they started reallocating the points so that people who came weekends got better deal and people who came weekdays got punished. The same ressie I could have gotten in 2009 for 200pts will cost me around 250 in 2011.... and the fact is they can keep raising it as long as the overall point usage doesn't change. So our dilemna is when will this new approach end .. or will it? How many points will be enough for us to vacation? About the only good news is they have it now so that weekdays and weekends are almost identical (about a 9-10% difff) so they can't punish me too much more. Unless of course, they figure a way to make weekdays higher than weekends 
We hope this settles down this next year and we will addon in 2011/2012
4 - How many points do you eventually want?
Honestly, we were told we had all we would ever need, but clearly that didn't work out. We only want maybe another 100 points max (total of 250-300)
We have just been trying to work through what our ideal number of points is going to end up being.
